Official record, complete with supporting evidence, states that Warbeck was a pretender to the English throne, the son of a customs‘ officer from Tournai in Belgium who was taken up by Yorkists when his resemblance to the younger of the missing princes in the Tower, Richard Duke of York, was noticed during a visit to Ireland.
He was the apprentice of Pregent Meno, a Breton merchant and when he arrived in Cork in 1491 his princely looks and manners were spotted whilst modeling the silks that his master was selling.
Perkin’s first stop in Europe in 1491 was at the court of Margaret of Burgundy where the aunt of the princes in the Tower recognized Perkin as her younger nephew. She claimed to recognize him from his knowledge of life in the Royal Household and from birthmarks. Perkin said that he should have been murdered but that the would be killer took pity on him. Whether she believed that Perkin was Richard is another matter entirely. The ‘diabolic duchess’ as the Tudor chroniclers labeled her offered sanctuary to erstwhile Yorkists and funded a variety of pretenders to the crown. So depending on the version of history you wish to believe she was either an aunt grateful for the return of her lost nephew or a hater of Henry VII grooming young Perkin for the role of a lifetime.
